SpletExpected ECG Changes in the Normal Heart. The altered action potential duration, conduction velocity, and contractile velocity associated with the increase in heart rate during exercise results in a number of ECG changes in normal people, including the following: RR interval decreases; P-wave amplitude and morphology undergo minor … Splet• At least one common ECG lead must be deemed acceptable for all tested postures. At a minimum, Supine and Standing/Sitting postures must be tested. Reasons for failure include: R waves too small The average amplitude of the R wave peaks was too small Score too low due to large R waves The average amplitude of the R-wave peaks was too large
